Environmental Assessment for Proposal To Construct Odor Treatment Units for the Potomac Interceptor Sewer and Improvements to a Parking Area and Two New Comfort Stations for the C&O Canal National Historical Park

Pursuant to Council on Environmental Quality regulations and National Park Service policy, the National Park Service announces the availability of an Environmental Assessment for the construction of four odor treatment units for the Potomac Interceptor (PI) sewer and improvements to a parking area and two new comfort stations for the C&O Canal National Historical Park (CHOH). In public use areas along the CHOH and the Clara Barton Parkway (which is administered by the George Washington Memorial Parkway (GWMP)), odorous air is intermittently exhausted from the PI sewer due to several dynamic hydraulic changes in the PI. Sewer odors emitted from the PI have resulted in the completion of an odor study, the implementation of interim odor controls, and the development of the long-term odor abatement program for several areas of the PI. This Environmental Assessment examines several alternatives for implementing four odor control facilities to control nuisance odors along the CHOH and the Clara Barton Parkway, as well as to indicate environmental impacts of the proposed construction of two comfort stations in CHOH access areas, and to improve the parking area at the Anglers Inn C&O Canal
